Check (California) @2

Check is named for the apparent check mark on the right fluke, likely the result of a killer whale interaction. Check suffered an extended entanglement between at least October 2024 and April 2025, cut free by an entanglement response team in Monterey Bay, California. For Happywhale, Check goes right back to the beginning of this system, the 2nd whale entered into the now-global database. This whale is known from research conducted by Cascadia Research Collective and collaborators, and is known in Mexico to ECOBAC from the photo-identification catalog of humpback whale of Banderas Bay, Mexico (FIBB catalog). Known as male from a biopsy sample collected by Proyecto Megaptera El Salvador and PRIMMA 01/20/2024 and analyzed at Dr. Omar Chassin’s lab (UMSNH).
